BAG FASTENER.

Application filed December 11, 1922. Serial No. 606,097.

T 0 all whom t may concern Be it known that I, FRANZ A. FULLER, acitizen of the United States, residing at (Newark, in the county ofEssex and State of New Jersey, have invented certain new "and usefulImprovements in Bag Fasteners,

of which the following is a specification.

This invention relates to improvements in fastening devices for bags,using the term in its generic sense, whereby the same is prevented fromopening until the locking means are released. Y

One of the objects of the invention is to provide a fastener of widerutility and more general adaptability than is usual.

Another purpose is to produce a fastener of exceptional simplicity andfewness of parts and these parts integrally inter-con nected withoutsolder, rivets, screws, or like securing devices.

A further aim is in the provision of a neat appearing, compact andstrong fastener, easy to apply and convenient to operate.

These and similar aims, objects and purposes are accomplishedby thenovel design, construction and arrangement of parts hereinafterdescribed and shown in the accompanying drawing, constituting anessential part of the disclosure, and in which zi Figure 1 is a frontelevational view showing a fragment of bag and illustrating theapplication of the invention thereto.

Figure 2 is a collective view in perspective of the several parts of thefastener prior to assemblage. e A

Figure 3 is a transverse sectional view of the fastener as assembled.

Figure 4 is a perspective view of the keeper member in detail.

Figure 5 .is a transverse sectional View of the same showing the mannerin which it is attached.

y Figure 6 is a similar view of the same as fully engaged.

In Figure 1 of the drawing a container of the bag, purse or portfoliotype is indicated, the body or main portion being designated by thenumeral 10 and the flap or cover portion by 11.

The fastener, shown attached to the portion 10, consists of a hollowrectangular casing having a level top or escutcheon plate12 from whichdepends a circumj acent flange 13 .flaring Slightly .Outward at both,Sides ,and

ends, the edges ofthe flange resting directly upon the fabric of thecontainer.

Within this casing is a plate 14 having upturned front and rear flanges15 suited vto engage within the corresponding sides of the casing, theedgeso-f the ianges being seated against the under side of the plate 12.

Similar raised flanges 16 are provided at the ends of the plate 14, thesame having lateral outstanding wings 17 parallel with the plate 14 andlevel with the edges of the front and rear flanges.y

Midway in the length of the wings 17 are continuing extensions 18 havingdownturned flanges 19 spaced to closely fit tightly within the endflanges 13 of the casing.

When so fitted the elements 19 are held in position by folding lugs 20,formed integral with the end flanges 13, of the casing, overv the edgesand inner sides of these elements, clamping the plate 14 rigidly to thecasing.

It is to be noted that the height of the elements 19 kis such that whenthe lugs 20,

which are nicked as at 21, are folded over plate 14 by shearing andbending the same upward as shown. Y

Similar lugs 26 formed in like manner ea:- tend longitudinally to act asstops for the slide, the rear of which is reduced in thickness forming aneck 27 leading to an integral raised circular hollow head 28.

Said neck 27 projects out through an opening 29 in the plate 12, coveredby the head, into the lower open part of which eX- tends a forwardlyextending prong 30 connected by the riser 81 with the plate 12, theprong and riser being formed from the material sheared in producing theopening 29.

Inside the head or knob 28 is a compression spring 32, one end.encircling the prong 30, abutting the rise-r 31 and the other en thesaine toward the fronl of the Yfastener, its action being limited bycontact ot the neck 2T with the front end ot the opening 29.

ilhe forward end of the plate 24 contains a recess 33 the inner edge otwhich is pressed by the spring past the corresponding edge of an opening34 in the plate l2, there being registering opening in the plate 14.

The keeper, shown `in Figs. 4, and 5 consists of a sheet of metal bentalong its inedian line to produce outer and inner elements respectivelyand 4l, thc entire` inargin of these elements being depressed as at 42and 43.

The front or outer plate is shear-ed triangularly as at 44-to producesharp spurs 45 adapted to pierce the material ll, strike upon the innersurface of the mating inember 4l and by it be deflected and clinched inthe material causing it to fill the bight of the loop 46 produced bybending the plate and becoming securely attached therein.

A flat post 47 is rigidly fixed centrally of' the front element 40 toextend outwardly at a right angle, the outer end of the post beingcurved or bevelled and its front edge provided with a recess or catch48.

lin operation, the parts being atl'zached in the manner described theflap ll is brought over the element 10 in such manner that the post 47is caused to enter the opening 34.

Upon the application of suitable pressure the curved end of the postwhenin contact with the edge of the recess 33, moves the plate. 24 and head28 rearwardly opposing the spring 32, until the recess 48 permits theplate to move forward engaging in the recess and thus positivelylockii'ig the parts together, the end of the post at that time beingentered in the opening 35.

To release the keeper it is merely necessary lo retract the head 2S toits limit/ thereupon freeing the plate 24 from the recess 4S in the postand separating the parts in the usual manner.

Thus the entire fastener mechanism consists of oni)7 three pieces, aspring and a sub# stantially integral keeper, the construction of whichis essentially simple.

As changes ot construction could be made within the scope of theinvention. it is intended that all matter contained in the foregoingdescription or shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent, is z l. A bag fastener comprising a pair etspaced plates, respectively inner and outer rigidly interengaged attheir oppositely flanged edges and containing` registering openings, akeeper having` an element enter?- able in the mentioned openings, saidelement being recessed, a slide movable in the space between saidplates, said slide having a part engageable in the recess of said keeperelement, a hollow circular head formed on said slide, said headextending through the ou? plate into position for operation, and meansin said head adapted to normally move said slide into engaging positionwith said keeper.

2. A bag fastener comprising upper and lower plate members spaced apartand containino` registering openings, iianges formed with each member tocause rigid interengagement, a slide movable between said plate members,means for guiding and means for limiting the movement of said slideformed on said lower member, said slide normally projecting partiallyinto the space between the mentioned openings, a head formed on saidslide, said head extending accessibly through an opening in the upper ofsaid plate members, and means for resiliently pressing said slide intoengaging position.
